  • Stable waterborne polymer compositions containing poly(alkylenimines)
    Patent number: 6649679
    Abstract: This invention provides stable waterborne polymer compositions, which are stabilized against gelling, comprising a stable waterborne polymer composition having a Tg of greater than about 0° C. and comprising an acetoacetoxy-type functional polymer, a poly(alkylenimine), and a nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. The waterborne polymer compositions of the invention are particularly useful in a variety of adhesive formulations such as pressure sensitive adhesives, laminating adhesives, and the like. Methods of making stable waterborne polymer compositions are also disclosed.
    Type: Grant

  • Stable waterborne polymer compositions containing poly(alkyleneimines)
    Patent number: 6201048
    Abstract: This invention provides waterborne polymer compositions stabilized against gelling due to the addition of a poly(alkylenimine) by post addition of certain anionic surfactants. The waterborne polymer compositions of the invention are useful in a variety of coating formulations such as, for example, paints, inks, sealants, textile back coatings, adhesives and the like. Methods of making stable waterborne polymer compositions are also disclosed.

  • Stable low foam waterborne polymer compositions containing poly(alkyleneimines)
    Patent number: 5990224
    Abstract: This invention provides low foam waterborne polymer compositions stabilized against gelling due to the addition of a poly(alkylenimine) by addition of surfactants. Preferably, the surfactants are nonionic surfactants having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. Polymerization in the presence of phosphate surfactants has been found to yield low foam polymers. These stable low foam polymer compositions are useful in a variety of coating formulations such as, for example, paints, inks, sealants, textile backcoatings, adhesives and the like. Methods of making stable low foam polymer are also disclosed.

  • Self-crosslinking aqueous dispersions
    Patent number: 5919716
    Abstract: The present invention is directed to polymer compositions containing a vinyl polymer component (A), formed by polymerization of .alpha.,.beta.-ethylenically unsaturated monomers, one which contains at least one hydroxyl group and one which contains no hydroxyl groups; a crosslinker component (B); an additive component (C); and a solvent component (D). The composition is useful for backcoating woven substrates and as a binder composition for non-woven substrates.
